Research and Application of Switchgear Dehumidification Plus Nitrogen Positive Pressure System
Jiangsu Power Grid is mostly located in humid and rainy region of the Yangtze River area,and HV switchgears of the network have long been affected,resulting in the internal environment deterioration and severe moisture erosion,vulnerable to insulation reduction and frequent discharge,even worse explosions,great threat to the security of personnel and equipment.Therefore,this paper presents a method that can completely eliminate the occurrence of moisture condensation phenomenon-switchgear dehumidification plus nitrogen positive pressure system,which can discharge the vapor of the air into the outside completely by an effective means,keeping a low dew point of the drying cabinet and forming an effective protection for switchgears.
